GIA low value (≤55) means a gradual rise in blood sugar — the most suitable range for diabetes and insulin resistance.
Adeni Fish Stew (Matfaya)
Matfaya is an Adeni fish dish from the coast of southern Yemen, in which the fish is marinated with Adeni basbas and lemon, then cooked over a sauce of onion and tomato in a pan until done.
It is served with muaddas rice or Adeni rashoush bread.
Clean the fish fillets and soak them in water with salt and vinegar for ten minutes, then drain them, because this soak cleans the fish and reduces its sea odor.
Marinate the fish with the Adeni basbas, crushed garlic, lemon juice, and half of the cumin and coriander, and leave it for half an hour, because a sufficient marinade lets the fish absorb the flavor before cooking.
Heat the oil over medium heat and saute the onion and green pepper until they soften and turn golden, because sauteing builds the base of the sauce and softens the pepper.
Add the grated tomato, tomato paste, the rest of the cumin and coriander, and the water, and cook for about ten minutes until the sauce thickens, because cooking the tomato removes its raw acidity and concentrates the flavor.
Place the fish fillets in the pan on top of the sauce and cover them with the liquid, and cook covered over low heat for about twenty minutes until the fish is cooked and its interior reaches 63 Celsius (145 Fahrenheit), because slow covered cooking cooks the fish evenly and keeps it tender.
Scatter the chopped fresh coriander over the dish and serve it hot with rice or rashoush bread, because the fresh coriander adds a refreshing aroma that balances the sharpness of the basbas.
The glycemic index (GI) measures how quickly a food raises blood sugar, while the glycemic load (GL) measures how much a full serving raises it. Together they give the complete picture.
A low value (≤55) means a gradual rise in blood sugar — the most suitable range for diabetes and insulin resistance.
Glycemic load reflects the impact of the full serving. To lower it: take half a serving, or pair the recipe with a source of protein and fiber.
* Percent Daily Values are based on a 2,000-calorie diet per FDA food-label reference values — your daily needs may be higher or lower. Values are derived from the recipe's ingredients via the USDA database.
The most common problems when preparing Adeni Fish Stew (Matfaya), and how to fix them:
Cook it covered over low heat without stirring, and set it on top of the sauce rather than mixing it in.
Cook the tomato longer before adding the fish so the water evaporates and it thickens.
Reduce the basbas and green pepper, and add more tomato to soften the heat.
Keep it in an airtight container for up to two days, and reheat it gently over low heat.
Freeze it for up to a month, and thaw it in the refrigerator before reheating to preserve the fish texture.
| Original Ingredient | Tested Substitute | Ratio | Flavor Difference |
|---|---|---|---|
| Adeni basbas | ground hot red pepper + garlic + coriander | 20 g + 10 g + 5 g | A close blend when ready-made basbas is unavailable, with a difference in depth. |
| fish fillets (thamad or direk) | hammour or sea bream | same weight | Firm fish that hold up to cooking in the sauce. |
| tomato paste | extra grated tomato | 120 g instead of 30 g | A natural alternative when paste is missing, with a slightly longer cooking time. |
| lemon juice | white vinegar | 20 ml instead of 30 ml | Gives the same acidity with a sharper flavor. |
| Ingredient | Half (two servings) | Base (4 servings) | Double (8 servings) |
|---|---|---|---|
| fish fillets | 250 g | 500 g | 1000 g |
| chopped onion | 125 g | 250 g | 500 g |
| grated tomato | 150 g | 300 g | 600 g |
| Adeni basbas | 30 g | 60 g | 120 g |
| crushed garlic | 10 g | 20 g | 40 g |
| hot green pepper | 20 g | 40 g | 80 g |
| lemon juice | 15 ml | 30 ml | 60 ml |
Adjust the amount of basbas to your desired heat; it is the soul of the Adeni dish and gives it its color and flavor.
